Simply put, the core difference between software and IT companies is that software companies create, change or maintain useful products. IT companies ensure that all systems, devices and software work together to help people get things done.

IT services are based on the use of information technology and support business processes in the company. They are defined by a combination of people, processes and technologies and should be clearly defined using Service Level Agreements (SLAs). In this way, they define all hardware and software, cloud and infrastructure components in the company - from the telephone system to the ERP system according to a specified IT service catalog.
